A matter entity requires the presence of fermions without excluding the presence of real or virtual fundamental bosons parts that are responsible for the interactions between the (real) fundamental fermions. The class of physical objects that have some fermionic quantum parts. The interpretation of the term "matter" is not univocal. Several concepts are labelled with this term, depending on the field of science. The concept mass is sometimes related to the term "matter", even if the former refers to a physical quantity (precisely defined by modern physics) while the latter is a type that qualifies a physical entity. It is possible to identify more than one concept that can be reasonably labelled with the term "matter". For example, it is possible to label as matter only the entities that are made up of atoms. Or more generally, we can be more fine-grained and call "matter" the entities that are made up of protons, neutrons or electrons, so that we can call matter also a neutron radiation or a cathode ray. A more fundamental approach, that we embrace for the EMMO, considers matter as entities that are made of fermions (i.e. quarks and leptons) requiring their presence, without excluding particles like the W and Z bosons that possess some mass, but are not fermions. Antimatter is a subclass of matter. Matter includes ordinary- and anti-matter. It is possible to have entities that are made of particle and anti-particles (e.g. mesons made of a quark and an anti-quark pair) so that it is possible to have entities that are somewhat heterogeneous with regards to this distinction.
